What Is ASTM C373 Ceramic Tile Water Absorption Bulk Density?
ASTM C373 evaluates water absorption and bulk density of ceramic and glass tiles to assess their quality, porosity, and durability. The test determines how much water a tile can absorb, which directly impacts strength, frost resistance, and long-term performance.
This method is widely used in construction and tile manufacturing industries. It helps classify tiles and ensures they meet the required standards for indoor and outdoor applications.
Applications and Benefits of ASTM C373 Ceramic Tile Water Absorption Bulk Density Testing
Scope
ASTM C373 measures the percentage of water absorbed by ceramic and glass tiles after immersion. It also determines bulk density and apparent porosity for quality evaluation.
The test evaluates:
- Water absorption percentage of tiles
- Bulk density and apparent porosity
- Material compactness and quality
- Suitability for different environments
- Durability and performance characteristics
Applications
- Ceramic and porcelain tiles
- Glass tiles and vitrified tiles
- Floor and wall tiles
- Construction and architectural materials
- Quality control in tile manufacturing
- Material classification and grading
Benefits
- Determines tile quality and durability
- Helps classify tiles based on absorption
- Supports material selection for applications
- Ensures compliance with construction standards
- Enables comparison of tile performance
Our ASTM C373 Testing Procedure
Sample Preparation
Tile specimens are cleaned, dried, and weighed.
1Water Immersion
Samples are immersed in water (often boiling) for a defined duration.
2Saturation Measurement
Saturated weight is recorded after immersion.
3Data Recording & Evaluation
Water absorption percentage and density are calculated.

ASTM C373 Ceramic Tile Water Absorption Bulk Density FAQs
The ASTM C373 test method is used to determine the water absorption, bulk density, apparent porosity, and apparent specific gravity of fired unglazed whiteware products, glazed or unglazed ceramic tiles, and glass tiles.
The ASTM C373 test is important, as it determines most of the important physical data on tiles. This helps manufacturers maintain their products in conformance with the industry's minimum standards regarding durability, performance, and safety. These standards are particularly crucial in the case of tiles used in settings where resistance to moisture and strength are among the major concerns.
The ASTM C373 test is essential to determine the tiles' most critical physical data.
